Hey all, having read the threads on rear windows, I bought some RainX and it's great, the rain just falls off. I put it on half of my windscreen too to see if it really works and the rain just disappears. I barely need to use my wipers. 
So then I thought, if I polished the car in it, would it stop it getting so dirty as the dirty rain would just fly off? Or would it damage the paintwork?
Has anyone tried it? What do you think?
